Cortical Atrophy

Cortical atrophy is a condition where the outer layer of the brain, called the cortex, shrinks or thins. This can lead to various cognitive and neurological problems. Understanding its causes, symptoms, diagnosis, and treatment is essential for managing the condition effectively.

Cortical atrophy refers to the shrinking or thinning of the outer layer of the brain, known as the cortex. This can lead to problems with memory, thinking, and movement.

Types:

1. Generalized cortical atrophy: Affects large areas of the brain’s cortex.
2. Focal cortical atrophy: Involves specific regions of the cortex.

Causes:

1. Aging: Natural aging processes can lead to cortical atrophy.
2. Alzheimer’s disease: Progressive brain disorder causing memory loss and cognitive decline.
3. Frontotemporal dementia: Affects personality, behavior, and language.
4. Parkinson’s disease: Movement disorder that can lead to cognitive decline.
5. Huntington’s disease: Genetic disorder causing involuntary movements and cognitive decline.
6. Traumatic brain injury: Head injuries can damage the brain’s structure.
7. Stroke: Interruption of blood flow to the brain can lead to tissue damage.
8. Multiple sclerosis: Autoimmune disorder affecting the central nervous system.
9. Alcohol abuse: Excessive alcohol consumption can damage brain cells.
10. Chronic stress: Prolonged stress may contribute to cortical atrophy.
11. Malnutrition: Poor nutrition can affect brain health.
